Lubricant Fluid Films With Directional Variable Viscosity

Abstract

A new rheological model for lubricants containing additives having long molecules is presented. The viscosity of the fluid is assumed to depend on the angle between the viscous forces and the velocity vector at each point in the lubricating film. The characteristics and consequences of this model are discussed qualitatively and quantitatively. Results far a finite slider bearing lubricated with such a lubricant are presented.
